I .To all whom it may concern:

Be it known that I, MATTHEW HowARD REED, a citizen of the United States, residin -at-.Avalon, in the county of Allegheny an ,State of Pennsylvania, have invented certain new'and useful Improvements in Coin-Controlled Weighing Apparatus, of which the following is a specification, reference being had therein to the accompanyin drawings, forming a part of this specification, in Which-- Figure, 1 is a vertical sectional view through the operative portion of my inven- Fig. 2 is a detail sectional view, on an enlarged scale, indicated by the line II II of Fi 1. .in icated by the line III III of Fig. 1.

.My invention consists of an im roved coin-controlled weighing a paratus aving for-it's object to register t e weight of the operator upon de ositing a coin of proper denomination wit in certain predetermined limits, provided with selective mechanism arranged to be adjusted by the operator,

,- coin-released indicating devices adaptc to show within a certain ran e the accuracy of the selection, and means or retaining or returning the coin dependent on the. degree of movement of said indicating devices.

' Referring to the drawings, 2 is a platformscale of usual construction provided with scale-levers,.&c'., and 'a steelyard-rod 3, ex-

tending up through a hollow post 4, on which. is mounted the case or housing 5, within. 4; which is contained the mechanism of my vention. The steelyard-rod 3 is connected with a steel lever 6, which in turn is connected by rod 7 with one end of a poise-beam 8, hung in the usual manner and provided with a poise 9.

10 is a variable counterpoise pivotally suspended by a hook 11 from the outer end of earn 8, fulcrumed at 12 at the extremity of rigid anchor loop or hook 13 and provided with a termina point 14. This variable counterpoise is adapted to point to zero when the'poise 9 is set to the exact weight of the operator; but to indicate upon a dial 15 more orless than said indicated weight within limits corresponding to the number of pounds, more or less, that the weight of the operator exceeds or falls short of the weight indicated by the poise.

The variable counterpoise is normally maintained at zero, as in Fig. 1, by scissorarms 16 16, pivoted at 17 to a stationary pin-bearing adapted to close together under action of spring 18 and bear at both sides against a pm 19, secured to the counterpoise 10, thus centering it, the arms also abutting against a limiting-stop 20. 21 is a coinchute registering with an insertion-opening 22, an intervening gate 23 being pivoted at 24 and provided with a portion extending out into range of a closing-door 25, forming a ortion of the front of case 5. (See Fig. 1 I.) Vhen the door is closed, the slot is open, but when the door is' open the ate closes the slot, preventing operation 0 the machine. By this means the device cannot be operated until the door is closed.

26 is a vertically-movable bar adapted to be depressed by a latch 27, pivoted to the extremity of an arm 28 and engaging pinabutment 29 on bar 26 to throw it down when the dooris closed, the arm 28 swinging around and drawing the latch 27 off of the pin after it has been sufhciently depressed. At the proper point ofdepression a lug 30 on bar 26 1s engaged by a latch 31 on lookinglever 32, pivoted at 33, pressed upward by spring 34, and extending out underneath the end of the poise-beam. When the weight of the operator is removed, the beam falls, strilring lever 32 and releasing bar 26, which is then thrown up by spring 35, engaging the arm 36, pivoted at 37 Springs 18 are mounted on arm 36, and when the arm rises these springs exert pressure upon the scissorarms 16 to close them and cause the counterpoise 10 to assume the zero position.

and of the poisebearn, so

rise, returning t On return or downward i'novcmcnt of the bar the sr-issorarms are pulled apart by the springs, thus permitting the variable counterpoise to operate through its range of movement when released, as hereinafter described.

38 is a movable coin-chute pivoted at 39, provided with a lockin -trigg g:cr 40, adapted. to enter recesses 41 in t 1e back ends of arms 16, as in Fig. 1, so as to hold these arms closed. The coin-chute 38 extends into the path of chute 21 and is so balanced that the weight of the coin depresses it, as in Fig. 4, throwing the trigger out of the notches and unlocking the mechanism. Chute 38 in turn delivers into a chute 42, the. end of which terminates above the money-drawer 4,3.

44 is a battle-plate sus )ended from counter oise 10 and provided with a slot 45 of suliici'ent length to register with the end of chute 42 when the countcrpoisc is at zero or, say, within one pound oi" it either way. Within these limits it will be seen that the coin will pass through said opening and vout through channel 46 and opening 47 in the front of the case, being thus returned to the operator. In other cases, however, the coin will strike the bathe-plate above or below its slot and will be thrown back into the money drawer and retained.

If desired, other means may be emplo 'ed to interfere with and retain the coin w ion. the redetermined range of movement is exceer ed and to allow free passage of the coin to the exterior when sald limit is not exceeded, and it will be understood that I do not desire to be confined to the exact means which I have shown and described for this purpose. V

It is obvious also that the mechanism may be so constructed that the coin will always be reti 'ncd, as by omitting the slot from the hatlielate or by merely interposing the money-i rawer in the path of the coin from the chute 42, so as to receive it at all times.

For the purpose of preventing fraudulent use of the fmachine, as by another person getting on the scale, after one has been weighed, with him, I provide a tripping-.

lever 48, pivoted at 49am provided with an arm 50, extending down upon lever 32. The other end of lever 48 extends out over the that as it rises, due to the increased weight, the arm 50 is depressed, relcasin latch 31, allowing bar 26 to e counterpoisc to zero and rendering the machine inoperative until again released by a coin. it will thus be seen that the tripping-levers 32 and 48 will act to release the mechanism, so that the machine will be inoperative whenever the weight oi the operator exceeds or falls short of any pn'edetermined range more or less than zero.

the movable end of the poise-beam 8, so as to control the movement thereof and prevent too sudden vibrations in either direction. 4,

As shown in Fig. 9, the door 25 is roviglcd F with a window 52, which exposes t e poisebeam and poise, but prevents access thereto without opening of the door.

The 0 oration is as follows: The operator having opened .the door and set the poise to his resumed weight then closes the door and epresses the bar 26, throwing spring-pressure on the soissoU-BJIIIB l6, tending to open them when released by the looking-trigger 40. He then do osits the coin, which releases tri ger 40. lpon being released the pointo the variable counterpoise 14 indicates the correctness of the guess or variation, either more or loss, within an predeterminod lin1itas, say, five pounr s either way. Thus a premium is placed upon the -ability of the operator to guess his own weight approximately, and if he does not dose the correct weight is shown him for the cost of the coin, within the range referred to It will be understood that the range of travel of the counterpoise and also the range of indiatinggraduations of the dial 15 may be increased at will to suit difl'e'rent re uirements of use and that the arrangement 0 the graduations may be changed or varied within wide limits or to cooperate with the reading of the poise-beam, as may he desired or necessary to suit varying requirements.

The device may be changed or Varied to suit different applications or combinations with various ty 10s of scales by the skilled mechanic; butal such changes are to be considcred as within the scope of the following claims.
